I hope this works out... it would be amazing for Steemit if they can get an audience, and there's clearly a lot of people looking for a Twitter alternative.
My only concern is I don't really understand how they can justify their $12 million valuation. I really hope this isn't a case of too much hype.
I don't know about the technical stuff. I hope it will be another good way to add users to steem and have to community growing.
